A dihedral angle is the angle between two intersecting planes. It does not have a specific degree.
It is an acute angle.
Al you need to get is a protractor to measure it really. say you had a straight line you know how much that measures and you know how much the other angle measures so subtract it and you have the answer!
The converse statement is that if the angle is an obtuse angle then it measures more than 90 degrees. Does not add much by way of information but there you go!
Anything bigger than a 90 degree angle
1 minute of an angle is 1/60 of a degree. Minutes have no relationship with meters.

90 degrees
Anything bigger than a 90 degree angle
A right angle measures 90 degrees.
60 degree
The supplementary angle of 57 degrees is 123 degrees The complementary angle of 75 degrees is 15 degrees So: 123 minus 15 = 108 degrees
1 minute of an angle is 1/60 of a degree. Minutes have no relationship with meters.
180 degrees. An equilateral triangle measures 60 degrees at every angle.
The external angles of a polygon total 360° . Therefore each external angle of a regular decagon measures 360/10 = 36° Therefore each INTERNAL angle measures 180 - 36 = 144°
